DETAILED DESCRIPTION

Before an exemplary embodiment is described, a technique which is the premise of this exemplary embodiment will be described. FIG. 2 is a diagram illustrating an example of the relationship among an apparatus 100, an information processing apparatus 150, and a firewall 220. A case in which the information processing apparatus 150 manages, for example, an apparatus A 100A, an apparatus B 100B, and an apparatus C 100C in an office internal communication environment 210 as shown in FIG. 2 will be described, and typically said an office internal communication environment 210 is configured with a local area network (LAN). In many cases, the firewall 220 is located between the local area network (LAN) and the wide area network (WAN), and is installed in the office internal communication environment 210. Therefore, when the information processing apparatus 150 provided in a center collects information (for example, debug log information including a record for the generation of a failure in the apparatus 100 and a failure repair record) stored in each apparatus 100, it is difficult for the information processing apparatus 150 to take a leading role in communication with the apparatus 100. Therefore, communication between the apparatus 100 and the information processing apparatus 150 is established by polling communication from the apparatus 100. According to this structure, it is possible to secure the office internal communication environment 210, but it is difficult to transmit a processing request from the information processing apparatus 150 to the apparatus 100 until the apparatus 100 performs polling communication. Examples of the apparatus include image processing apparatuses (for example, a copier, a facsimile machine, a scanner, a printer, and a multi-function machine (for example, an image processing apparatus having two or more functions of a scanner, a printer, a copier, and a facsimile machine)) and other office apparatuses. Any apparatus may be used as long as it is connected through a communication line and transmits information stored therein to the information processing apparatus 150.

The information processing apparatus 150 has a function of collecting information stored in the apparatus 100. For example, the developer of the apparatus 100 may designate a collection target apparatus 100 and collect information from the apparatus 100, in order to use the information for investigation during failure response. The collection is performed as follows: an information transmission request is transmitted as an instruction from the information processing apparatus 150 to the apparatus 100 and the apparatus 100 receives the information transmission request and transmits information to the information processing apparatus 150. However, it is necessary to wait for the transmission of the information transmission request until the apparatus 100 performs polling communication. As shown in FIG. 2, when there is an apparatus-sent communication 231 from the apparatus B 100B, the information processing apparatus 150 is capable of transmitting an information processing apparatus-sent communication 232. An instruction to transmit information stored in the apparatus B 100B may be included in the information processing apparatus-sent communication 232, which makes it possible to transmit the information stored in the apparatus B 100B from the apparatus B 100B. However, when the apparatus-sent communication 231 has not been transmitted from the apparatus C 100C, an information processing apparatus-sent communication 250 transmitted to the apparatus C 100C is interrupted by the firewall 220.

A detailed example will be described.

In a case in which the period of polling communication from the apparatus from which information is desired to be collected is set such that the polling communication is performed once a day at 1:00 a.m., even when information is desired to be collected at 6:00 p.m., it is difficult to collect information until the apparatus performs polling communication at 1:00 a.m. the next day. Therefore, the collection of information is delayed from 6:00 p.m. to 1:00 a.m., that is, for 7 hours.

A case is considered in which, when there are apparatuses A, B, and C from which information is desired to be collected and the period of polling communication is set such that the polling communication is performed once a day at 1:00 a.m., information collection is performed on each apparatus considering the load of the network. The apparatuses A, B, and C perform polling communication at 1:00 a.m. the first day and an information transmission request is transmitted only to the apparatus A. The same operation is performed on the apparatus B at 1:00 a.m. the next day and is performed on the apparatus C at 1:00 a.m. the day after next. Then, it takes a minimum of three days to collect information from all of the apparatuses A, B, and C.

Next, exemplary embodiments of the invention will be described with reference to the accompanying drawings.

First Exemplary Embodiment

FIG. 1 is a conceptual module configuration diagram illustrating an example of a structure according to a first exemplary embodiment.

The term “module” refers generally to a component, such as logically separable software (computer program) and hardware. Therefore, a module in this exemplary embodiment indicates not only a module in a computer program, but also a module in a hardware structure. Thus, this exemplary embodiment relates to a computer program (including a program which causes a computer to perform each process, a program which causes a computer to function as each unit, and a program which causes a computer to implement the functions of each unit) that causes a computer to function as modules, a system, and a method. For convenience of description, as used herein, “store,” “be stored”, or the equivalents thereof mean that a computer program is stored in a storage device or is controlled such that it is stored in a storage device when the exemplary embodiment relates to the computer program. The module may be in one-to-one correspondence with a function. When modules are mounted, one module may be configured as one program, plural modules may be formed by one program, or one module may be formed by plural programs. Plural modules may be implemented by one computer, or one module maybe implemented by plural computers in distributed or parallel environments. One module may include other modules. Hereinafter, the term “connection” includes physical connection and logical connection (for example, the transmission and reception of data, instructions, and the reference relationship between data). The term “predetermined” refers to being decided prior to a target process. The term “predetermined” includes not only determination before a process according to the exemplary embodiment starts, but also determination according to situations and conditions at that time or situations and conditions up to that time before a target process after the process according to the exemplary embodiment starts. In addition, the sentence “when A is satisfied, B is performed” means that “if it is determined that A is satisfied, B is performed”. However, a case in which it is not necessary to determine whether A is satisfied is excluded.

The term “system” or “apparatus” includes a structure including, for example, one computer, hardware, and a device and a structure in which, for example, plural computers, hardware, and devices are connected to each other by a communication unit, such as a network (including one-to-one correspondence communication connection). In the specification, “apparatus” is synonymous with “system.” Naturally, the “system” does not include anything that is merely a social “structure” (social system) that includes artificial decisions.

For each process by each module or each process when plural processes are performed in a module, target information is read from a storage device and is then processed and the process result is written to the storage device. Therefore, in some cases, the description of reading information from the storage device before the process and writing the process result to the storage device after the process is omitted. The storage device may include, for example, a hard disk, a Random Access Memory (RAM), an external storage medium, a storage device through a communication line, and a register in a Central Processing Unit (CPU).

An information processing system according to the first exemplary embodiment includes plural apparatuses (FIG. 1 shows two apparatuses, that is, an apparatus 100 and an apparatus 120, but three or more apparatuses may be provided) and an information processing apparatus 150, as shown in FIG. 1. The information processing apparatus 150 manages the apparatus 100. The apparatus 100, the apparatus 120, and the information processing apparatus 150 are connected to each other through a communication line 199. As described above, there is a firewall and the apparatus 100 and the apparatus 120 are provided in the firewall. In addition, the apparatuses in the firewall are connected to each other through a communication line 198.

The outline of a process is as follows. When there is any communication (for example, polling communication or information transmission) from the apparatus in the firewall and the information processing apparatus 150 issues an instruction to transmit an information transmission request to another apparatus in the same firewall, the apparatus which has performed communication acquires the instruction and transfers the instruction to the apparatus, which is an instruction target.

Specifically, in a situation in which there are apparatuses A and B in the firewall and information stored in the apparatus A is desired to be collected, when there is polling communication from the apparatus B, the information processing apparatus 150 instructs the apparatus B to transfer the information transmission request to the apparatus A.

The apparatus 100 includes a communication module 102, a communication analyzing module 104, a log information collecting module 106, a log information storage module 108, and a transferring module 110.

The apparatus 120 includes a communication module 122, a communication analyzing module 124, a log information collecting module 126, a log information storage module 128, and a transferring module 130. Since the internal structure of the apparatus 120 is the same as that of the apparatus 100, the modules in the apparatus 100 will be described below.

The information processing apparatus 150 includes a communication module 152, a communication analyzing module 154, a plan making module 156, a plan making instruction module 158, an apparatus information storage module 160, a log analyzing module 162, and a log information storage module 164.

The apparatus 100 and the apparatus 120 are connected to the information processing apparatus 150 with the firewall interposed therebetween. Plural apparatuses 100 are provided in the firewall. When plural apparatuses 100 are distinguished from each other, in some cases, they are referred to as, for example, an apparatus 100(A) and an apparatus 100(B).

The communication module 102 is connected to the communication analyzing module 104, the log information collecting module 106, and the transferring module 110 and is also connected to the communication module 152 of the information processing apparatus 150 through the communication line 199. In addition, the communication module 102 is connected to the communication module 102 of another apparatus 100(B). The communication module 102 communicates with the information processing apparatus 150. For example, the communication module 102 performs polling communication from the apparatus 100 to the information processing apparatus 150 and receives a communication from the information processing apparatus 150. The communication module 102 of the apparatus 100(A) performs communication with another apparatus 100(B) and receives a communication from another apparatus 100(B). The communication module 102 of the apparatus 100(B) performs communication with another apparatus 100(A) and receives a communication from another apparatus 100(A).

The communication analyzing module 104 is connected to the communication module 102, the log information collecting module 106, and the transferring module 110. The communication analyzing module 104 analyzes the communication received by the communication module 102 from the information processing apparatus 150. It is determined whether the communication received by the communication module 102 of the apparatus 100(A) includes an instruction to request another apparatus 100(B) which is connected to the same firewall to transmit the information stored in the apparatus 100(B). In addition, the communication analyzing module 104 analyzes the communication received by the communication module 102 from the apparatus 100(A). It is determined whether the communication received by the communication module 102 of the apparatus 100(B) includes an instruction to request the transmission of the information stored in the log information storage module 108 of the host apparatus (apparatus 100(B)) to the information processing apparatus 150.

The log information collecting module 106 is connected to the communication module 102, the communication analyzing module 104, and the log information storage module 108. When the communication analyzing module 104 of the apparatus 100(B) determines that there is an instruction to request the transmission of the information stored in the log information storage module 108 to the information processing apparatus 150, the log information collecting module 106 transmits the information stored in the log information storage module 108 to the information processing apparatus 150 through the communication module 102 and the communication line 199.

The log information storage module 108 is connected to the log information collecting module 106. The log information storage module 108 stores, for example, debug log information about the apparatus 100.

The transferring module 110 is connected to the communication module 102 and the communication analyzing module 104. When the communication analyzing module 104 determines that the instruction to request another apparatus 100(B) connected in the same firewall to transmit the information stored in the apparatus 100(B) is included, the transferring module 110 transmits the instruction to another apparatus 100(B) through the communication module 102 and the communication line 199.

The communication module 152 is connected to the communication analyzing module 154 and the plan making module 156 and is also connected to the communication module 102 of the apparatus 100 through the communication line 199. The communication module 152 receives, for example, polling communication from the apparatus 100 to the information processing apparatus 150 and the information stored in the apparatus 100 and performs communication with the apparatus 100.

The communication analyzing module 154 is connected to the communication module 152, the plan making module 156, and the log analyzing module 162. The communication analyzing module 154 determines whether the communication module 152 receives, for example, polling communication from the apparatus 100(A). In addition, the communication analyzing module 154 determines whether the communication from the apparatus 100(B) includes the information stored in the apparatus 100(B).

The plan making module 156 is connected to the communication module 152, the communication analyzing module 154, the plan making instruction module 158, and the apparatus information storage module 160. When the communication analyzing module 154 determines that polling communication is received from the apparatus 100(A), the plan making module 156 transmits an instruction to request another apparatus 100(B) in the firewall including the apparatus 100(A) to transmit the information stored in the apparatus 100(B) to the apparatus 100(A) through the communication module 152 and the communication line 199.

In addition, when there are plural apparatuses 100(B) which request the transmission of information, the plan making module 156 makes a plan for a transmission order or a transmission date and time on the basis of a plan making instruction from the plan making instruction module 158. Then, the plan making module 156 transmits the instruction to the apparatus 100(A) through the communication module 152 and the communication line 199 according to the plan. In addition, the plan making module 156 may make a plan on the basis of the communication allowable range of the firewall and the capacity of the information transmitted by the apparatus 100(B). Then, the plan making module 156 transmits the instruction to the apparatus 100(A) through the communication module 152 and the communication line 199 on the basis of the plan. In addition, the plan making module 156 makes a plan using the information stored in the apparatus information storage module 160.

The plan making instruction module 158 is connected to the plan making module 156. The plan making instruction module 158 designates the apparatus from which information is to be collected on the basis of the operation of the operator (for example, the developer) for, for example, a keyboard, a mouse, or a touch panel. Then, the plan making instruction module 158 instructs the plan making module 156 to make a plane for an information transmission order or an information transmission date and time.

The apparatus information storage module 160 is connected to the plan making module 156. The apparatus information storage module 160 stores, for example, information about each apparatus 100. For example, the apparatus information storage module 160 stores a log information collection plan 600, a log information collection plan 700, an F-ID and IP address correspondence table 800, an F-ID and apparatus ID correspondence table 900, an F-ID and network allowable load correspondence table 1000, an IP address and log information capacity correspondence table 1100, and an apparatus ID and log information capacity correspondence table 1200.

The log analyzing module 162 is connected to the communication analyzing module 154 and the log information storage module 164. When the communication analyzing module 154 determines that the communication from the apparatus 100(5) includes the information stored in the apparatus 100(B), the log analyzing module 162 stores the information in the log information storage module 164. Then, the log analyzing module 162 analyzes the information stored in the log information storage module 164.

The log information storage module 164 is connected to the log analyzing module 162. The log information storage module 164 stores the information stored in the apparatus 100(B). In addition, the log information storage module 164 transmits the information to the log analyzing module 162.

FIG. 3 is a flowchart illustrating an example of a process according to the first exemplary embodiment (information processing apparatus 150).

In Step S302, the plan making instruction module 158 receives a plan making instruction input by the operation of the operator for, for example, a keyboard, a mouse, or a touch panel.

In Step S304, the plan making module 156 makes a debug log information collection plan using the information stored in the apparatus information storage module 160. The apparatus information storage module 160 stores the log information collection plan 600 or the log information collection plan 700, the F-ID and IP address correspondence table 800 or the F-ID and apparatus ID correspondence table 900, the F-ID and network allowable load correspondence table 1000, and the IP address and log information capacity correspondence table 1100 or the apparatus ID and log information capacity correspondence table 1200.

The debug log information collection plan to be made includes the transmission order of the apparatus 100 from which the debug log information is transmitted, or the apparatus 100 from which the debug log information is transmitted and the date and time (year, month, day, minute, second, millisecond, or a combination thereof) when the debug log information is transmitted. In addition, plural apparatuses 100 from which the debug log information is transmitted at the same time may be designated. That is, in the debug log information collection plan including the apparatuses 100 and the transmission order, there are plural apparatuses 100 with the same order. In the debug log information collection plan including the transmission date and time, there are plural apparatuses 100 with the same transmission date and time.

FIG. 6 is a diagram illustrating an example of the data structure of the log information collection plan 600. The log information collection plan 600 includes a No. field 610 and an IP address field 620. The No. field 610 stores the number of the apparatus 100. In addition, the No. field 610 may store the name of the apparatus 100. The IP address field 620 stores the IP address of the apparatus 100. In the debug log information collection plan, the IP address is designated. In this manner, the apparatus 100 receiving the debug log information collection plan specifies the apparatus 100 which will transfer a debug log information transmission request.

FIG. 7 is a diagram illustrating an example of the data structure of the log information collection plan 700. The log information collection plan 700 includes a No. field 710 and an apparatus ID field 720. The No. field 710 is the same as the No. field 610 of the log information collection plan 600. The apparatus ID field 720 stores the apparatus ID (in this exemplary embodiment, information capable of uniquely identifying the apparatus 100) of the apparatus 100. When the apparatus ID is designated in the debug log information collection plan, the apparatus 100 receiving the debug log information collection plan specifies the apparatus 100 which will transfer a debug log information transmission request.

The apparatus information storage module 160 may store only the log information collection plan 600 or the log information collection plan 700.

FIG. 8 is a diagram illustrating an example of the data structure of the F-ID and IP address correspondence table 800. The F-ID and IP address correspondence table 800 includes an F-ID field 810 and an IP address field 820.

The F-ID field 810 stores information (hereinafter, referred to as F-ID) capable of uniquely identifying the firewall in this exemplary embodiment. For example, information (client ID) capable of uniquely identifying a client or information (office ID) capable of uniquely identifying an office may be used as long as it corresponds to the firewall. The IP address field 820 stores the IP address of the apparatus 100 belonging to the firewall.

FIG. 9 is a diagram illustrating an example of the data structure of the F-ID and apparatus ID correspondence table 900. The F-ID and apparatus ID correspondence table 900 includes an F-ID field 910 and an apparatus ID field 920. The F-ID field 910 is the same as the F-ID field 810 of the F-ID and IP address correspondence table 800. The apparatus ID field 920 stores the apparatus ID of the apparatus 100 belonging to the firewall.

The F-ID and IP address correspondence table 800 and the F-ID and apparatus ID correspondence table 900 indicate the apparatus 100 belonging to the firewall. Therefore, an instruction may be given to the apparatus 100(A) such that another apparatus 100(B) with the same F-ID as that of the apparatus 100(A) which has performed communication, such as polling communication, transmits information to the information processing apparatus 150.

The apparatus information storage module 160 may store only the F-ID and IP address correspondence table 800 or the F-ID and apparatus ID correspondence table 900.

FIG. 10 is a diagram illustrating the data structure of the F-ID and network allowable load correspondence table 1000. The F-ID and network allowable load correspondence table 1000 includes an F-ID field 1010 and a network allowable load field 1020. The F-ID field 1010 stores F-ID. The network allowable load field 1020 stores the load (for example, the limit of communication capacity) which is allowed in the firewall.

FIG. 11 is a diagram illustrating the data structure of the IP address and log information capacity correspondence table 1100. The IP address and log information capacity correspondence table 1100 includes an IP address field 1110 and a log information capacity field 1120. The IP address field 1110 stores the IP address of the apparatus 100. The log information capacity field 1120 stores the capacity of the debug log information stored in the apparatus 100.

FIG. 12 is a diagram illustrating the data structure of the apparatus ID and log information capacity correspondence table 1200. The apparatus ID and log information capacity correspondence table 1200 includes an apparatus ID field 1210 and a log information capacity field 1220. The apparatus ID field 1210 stores the apparatus ID of the apparatus 100. The log information capacity field 1220 is the same as the log information capacity field 1120 of the IP address and log information capacity correspondence table 1100.

The F-ID and network allowable load correspondence table 1000, the IP address and log information capacity correspondence table 1100, and the apparatus ID and log information capacity correspondence table 1200 are for making the debug log information collection plan such that the load of the communication line in the firewall is reduced when the debug log information is transmitted from plural apparatuses 100 at the same time. That is, the capacity of the debug log information stored in the apparatuses 100 from which the debug log information is transmitted at the same time is extracted from the log information capacity field 1120 or the log information capacity field 1220, and the extracted capacity of the debug log information is added and compared with the load which is allowed in the firewall (the load extracted from the network allowable load field 1020). In this way, it is determined whether the debug log information is transmitted from plural apparatuses 100 at the same time.

The apparatus information storage module 160 may store only the IP address and log information capacity correspondence table 1100 and the apparatus ID and log information capacity correspondence table 1200.

In Step S306, the communication module 152 receives a communication from the apparatus 100(A). The communication may be the above-mentioned polling communication, other communications, or a communication from the apparatus 100(A).

In Step S308, the communication analyzing module 154 determines whether the debug log information is received. When the debug log information is received, the process proceeds to Step S310. In the other cases, the process proceeds to Step S312.

In Step S310, the log analyzing module 162 stores the received debug log information in the log information storage module 164 and analyzes the debug log information. Then, the process proceeds to Step S399 (end process).

In Step S312, the communication analyzing module 154 determines whether the F-ID of the apparatus which has performed transmission is in the made debug log information collection plan. When the F-ID of the apparatus is in the debug log information collection plan, the process proceeds to Step S314. In the other cases, the process proceeds to Step S316. That is, it is determined whether the debug log information collection plan made in Step S304 is capable of being applied to the apparatus 100 which has performed communication (another apparatus 100 in the firewall to which the apparatus 100 belongs).

In Step S314, the communication module 152 transmits the corresponding debug log information collection plan to the apparatus which has performed transmission. As the debug log information collection plan to be transmitted, an “instruction to request the apparatus 100(B) to transmit the debug log information stored in the apparatus 100(B)” which is a portion of the debug log information collection plan may be used.

In Step S316, the information processing apparatus 150 performs a process according to the content of the communication from the apparatus. For example, the information processing apparatus 150 performs a normal process according to polling communication.

After Step S310, the process proceeds to Step S399. However, the process proceeds to Step S312.

FIG. 4 is a flowchart illustrating an example of the process according to the first exemplary embodiment (apparatus 100(A)).

In Step S402, the communication module 102 performs communication with the information processing apparatus 150. The communication may be the above-mentioned polling communication, other communication, or communication from apparatus 100(A) to the information processing apparatus 150.

In Step S404, the communication module 102 receives a communication from the information processing apparatus 150.

In Step S406, the communication analyzing module 104 determines whether there is a debug log information transmission request. When there is a debug log information transmission request, the process proceeds to Step S408. In the other cases, the process proceeds to Step S412. That is, it is determined whether there is a debug log information transmission request for the apparatus 100(A), which is the host apparatus.

In Step S408, the log information collecting module 106 collects the debug log information stored in the log information storage module 108.

In Step S410, the communication module 102 transmits the debug log information to the information processing apparatus 150.

In Step S412, the communication analyzing module 104 determines whether there is a debug log information collection plan. When there is a debug log information collection plan, the process proceeds to Step S414. In the other cases, the process proceeds to Step S416. That is, it is determined whether a debug log information transmission request for another apparatus 100(B) is included.

In Step S414, the transferring module 110 transfers according to the debug log information collection plan. That is, the apparatus 100(A) transmits the debug log information transmission request for another apparatus 100(B) to the apparatus 100(B).

In Step S416, the apparatus 100 performs a process according to the content of communication with the information processing apparatus 150. For example, the apparatus 100 performs a normal process according to polling communication.

After Step S410, the process proceeds to Step S416. However, the process proceeds to Step S412.

FIG. 5 is a flowchart illustrating an example of the process according to the first exemplary embodiment (apparatus 100(B)).

In Step S502, the communication module 102 receives a communication from another apparatus (apparatus 100(A)). That is, the communication module 102 receives a communication from another apparatus (apparatus 100(A)) in the firewall to which the host apparatus (apparatus 100(B)) belongs.

In Step S504, the communication analyzing module 104 determines whether there is a debug log information transmission request. When there is a debug log information transmission request, the process proceeds to Step S506. In the other cases, the process proceeds to Step S510.

In Step S506, the log information collecting module 106 collects the debug log information stored in the log information storage module 108.

In Step S508, the communication module 102 transmits the debug log information to the information processing apparatus 150.

In Step S510, the apparatus 100 performs a process according to the content of communication with another apparatus. For example, a predetermined process is performed between the apparatus 100(A) and the apparatus 100(B).

The above will be described using a detailed example.

It is assumed that, in a situation in which there are apparatus A 100A and the apparatus B 100B in the office internal communication environment 210 and debug log information is desired to be collected from each device, the debug log information is collected from each apparatus considering a network load. When the apparatus A 100A performs polling communication with the information processing apparatus 150, a debug log information transmission request for the apparatus A 100A is transmitted to the apparatus A 100A. When receiving the debug log information from the apparatus A 100A, the information processing apparatus 150 instructs the apparatus A 100A to transfer the debug log information transmission request to the apparatus B 100B, in response to the debug log information. The apparatus A 100A transfers the debug log information transmission request to the apparatus B 100B on the basis of the instruction. The apparatus B 100B transmits the debug log information to the information processing apparatus 150 on the basis of the debug log information transmission request.

When 140-MB, 80-MB, 60-MB, and 120-MB debug log information items are desired to be collected from an apparatus A 100A, an apparatus B 100B, an apparatus C 1000, and an apparatus D 100D in the office internal communication environment 210 in which the amount of debug log information which is simultaneously transmitted is limited to 200 MB, respectively, first, a debug log information collection plan (a debug log information collection plan in which the debug log information is transmitted from the apparatus A 100A and the apparatus C 100C at the same time and is then transmitted from the apparatus B 100E and the apparatus D 100D at the same time) is made. When there is polling communication from any one of the apparatus A 100A, the apparatus B 100B, the apparatus C 1000, and the apparatus D 1000, the debug log information transmission request is transmitted to the apparatus A 100A and the apparatus C 100C according to the debug log information collection plan and is transmitted to the apparatus B 100B and the apparatus D 100D according to the reception state of the debug log information. Specifically, the debug log information transmission request for the apparatus B 100B and the apparatus D 100D is transmitted to one of the apparatus A 100A and the apparatus C 100C which has transmitted the debug log information whose reception by the information processing apparatus 150 has been delayed.

Another detailed example will be described with reference to FIG. 13.

The information processing apparatus 150 manages the apparatus ID and F-ID of the apparatus 100 in association with each other (the F-ID and apparatus ID correspondence table 900 shown in FIG. 9). In addition, the information processing apparatus 150 has the debug log information collection plan and the debug log information collection plan is made for each F-ID and may be searched for using the F-ID as a key.

A scene will be described in which there are an apparatus A 100A, an apparatus B 100B, an apparatus C 100C, an apparatus D 100D, and an apparatus E 100E in the office internal communication environment 210 of a given client and the debug log information is collected from the apparatus B 100B, the apparatus C 100C, the apparatus D 100D, and the apparatus E 100E among them.

The plan making module 156 registers a debug log information transmission request for the apparatus B 100B, the apparatus C 100C, the apparatus D 100D, and the apparatus E 100E in the debug log information collection plan.

When there is polling communication from the apparatus A 100A (Step S1302), the information processing apparatus 150 searches for an F-ID corresponding to the apparatus A 100A and also searches for the debug log information collection plan corresponding to the F-ID. Since the debug log information collection plan includes requests for the apparatus B 100B, the apparatus C 100C, the apparatus D 100D, and the apparatus E 100E to transmit the debug log information, the requests are transmission targets.

It is assumed that, in the office internal communication environment 210 with the F-ID, the simultaneous transmission of debug log information of 100 MB or more is limited considering the network load (the F-ID and network allowable load correspondence table 1000 shown in FIG. 10). The size of the debug log information is known in advance according to, for example, the IP address and log information capacity correspondence table 1100, the apparatus ID and log information capacity correspondence table 1200, or the type of apparatus. It is assumed that the sizes of the debug log information items which are desired to be acquired from the apparatus B 100B, the apparatus C 100C, the apparatus D 100D, and the apparatus E 100E are 100 MB, 50 MB, 60 MB, and 40 MB, respectively. The order of the apparatus B 100B→(the apparatus D 100D+the apparatus E 100E)→the apparatus C 100C is calculated as the transmission order in which the collection of the debug log information is completed in the shortest time on the basis of the network load limit and the size of the debug log information (information items in the parentheses are transmitted at the same time). The debug log information collection plan is made of the basis of the transmission order.

The information processing apparatus 150 instructs the apparatus A 100A to transfer the debug log information transmission request to the apparatus B 100B on the basis of the made debug log information collection plan (Step S1304).

When transmitting the debug log information transmission request to the apparatus B 100B, the apparatus A 100A needs to specify the IP address of the apparatus B 100B and establish communication. As the specifying method, any of the following methods is performed.

(1) The information processing apparatus 150 manages the IP address of the apparatus (the log information collection plan 600 shown in FIG. 6) and gives an IP address to the debug log information transmission request. The apparatus (in this case, the apparatus A 100A) transferring the debug log information transmission request transfers on the basis of the IP address given to the debug log information transmission request.

(2) The information processing apparatus 150 manages the apparatus ID (the log information collection plan 700 shown in FIG. 7) and gives an apparatus ID to the debug log information transmission request. The apparatus (in this case, the apparatus A 100A) transferring the debug log information transmission request makes a list of the IP addresses of the apparatuses in the network (office internal communication environment 210) using a protocol, such as SNMP. The apparatus ID is capable of being acquired by any network unit and an apparatus, which is a transmission destination of the debug log information transmission request, is specified on the basis of the IP address list and the apparatus ID of the debug log information transmission request.

The apparatus A 100A establishes communication with the apparatus B 100E using the above-mentioned method and transfers the debug log information transmission request (Step S1306). The apparatus B 100B transmits the debug log information to the information processing apparatus 150 on the basis of the debug log information transmission request (Step S1308).

After receiving the debug log information from the apparatus B 100B, the information processing apparatus 150 instructs the apparatus B 100B to transfer the debug log transmission request to the apparatus D 100D and the apparatus E 100E as a response, on the basis of the debug log information collection plan (Step S1310).

The above-mentioned operation is repeatedly performed until the debug log transmission request is removed from the debug log information collection plan. Specifically, the following process is performed.

In Step S1312, the apparatus B 100B transfers the debug log information transmission plan to the apparatus D 100D.

In Step S1314, the apparatus B 100B transfers the debug log information transmission plan to the apparatus E 100E.

In Step S1316, the apparatus D 100D transmits the debug log information to the information processing apparatus 150.

In Step S1318, the apparatus E 100E transmits the debug log information to the information processing apparatus 150.

In Step S1320, the information processing apparatus 150 instructs the apparatus E 100E to transfer the debug log information transmission plan to the apparatus C 100C.

In Step S1322, the apparatus E 100E transfers the debug log information transmission plan to the apparatus C 100C.

In Step S1324, the apparatus C 1000 transmits the debug log information to the information processing apparatus 150.

When the collection of the debug log information from the apparatus D 100D is not needed before the transmission instruction is transmitted to the apparatus B 100B (specifically, the plan making instruction module 158 receives an operation for deleting the “collection of the debug log information from the apparatus D 100D” from the operator), the debug log transmission request for the apparatus D 100D is deleted from the debug log information collection plan and the debug log information collection plan is updated to the apparatus B 100B→(the apparatus C 100C+the apparatus E 100E). In this case, the debug log transmission request to instruct transmission to the apparatus B 100B becomes a debug log transmission request for the apparatus C 100C and the apparatus E 100E.

In addition, there is a case in which a debug log transmission request for the apparatus A 100A is additionally needed (specifically, a case in which the plan making instruction module 158 receives the operation of the operator adding “the collection of the debug log information from the apparatus A 100A”). When the size of the debug log information which is desired to be collected from the apparatus A 100A is 50 MB, the debug log information collection plan is updated to the apparatus B 100B→(the apparatus D 100D+the apparatus E 100E)→(the apparatus C 100C+the apparatus A 100A).

As such, when the collection of the debug log information does not start even during the execution of the debug log information collection plan, the debug log transmission request in the debug log information collection plan may be deleted and the debug log information collection plan may be made again. In addition, a debug log transmission request may be added even during the execution of the debug log information collection plan and the debug log information collection plan may be made again.

Second Exemplary Embodiment

The structure of a second exemplary embodiment is the same as the module structure according to the first exemplary embodiment shown in FIG. 1.

A communication analyzing module 104 of an apparatus 100(A) determines whether a communication module 102 receives a plan for a transmission order or a transmission date and time from an information processing apparatus 150.

When the communication analyzing module 104 determines that the plan for the transmission order or the transmission date and time is received from the information processing apparatus 150, a transmitting module 110 of the apparatus 100(A) transmits an instruction (information transmission instruction) to the apparatus 100(B) in the plan through the communication module 102 and a communication line 199 on the basis of the plan.

A communication module 102 of the apparatus 100(B) receives the instruction from the apparatus 100(A).

A communication analyzing module 104 of the apparatus 100(B) determines whether the communication module 102 receives the instruction (information transmission instruction) from the apparatus 100(A).

When the communication analyzing module 104 determines that the instruction (information transmission instruction) is received from the apparatus 100(A), a log information collecting module 106 of the apparatus 100(B) transmits information stored in the log information storage module 108 to the information processing apparatus 150 through the communication module 102 and the communication line 199. Then, the information collecting module 106 transmits the information which has been stored in the log information storage module 108 of the host apparatus (apparatus 100(B)) and then transmitted to the information processing apparatus 150 to the apparatus 100(A) which has transmitted the instruction through the communication module 102 and the communication line 199.

In the first exemplary embodiment, the information processing apparatus 150 controls the collection of information from the apparatus 100(B). However, in the second exemplary embodiment, after receiving an instruction (instruction including a plan) from the information processing apparatus 150, the apparatus 100(A) controls the transmission of information to another apparatus 100(B). First, the apparatus 100(A) transfers an instruction (instruction to transmit information to the information processing apparatus 150) to the apparatus 100(B). After transmitting the information stored in the log information storage module 108 to the information processing apparatus 150, the apparatus 100(B) notifies the apparatus 100(A) that the transmission of the information has been completed. Then, the apparatus 100(A) transfers the next information transmission instruction to another apparatus 100(C) on the basis of a transmission plan for the information transmission instruction (when the transmission plan is a plan for “the date and time”, for example, the following two methods are considered. The information transmission instruction is not transferred to another apparatus 100(C) immediately after information indicating the completion of transmission is notified to the apparatus 100(A), but the apparatus 100(A) transfers the information transmission instruction to the apparatus 100(C) at the date and time when the transmission of information to the apparatus 100(C) is required in the transmission plan. Alternatively, when information indicating the completion of transmission is notified to the apparatus 100(A), the information transmission instruction and the transmission plan are transmitted to the apparatus 100(C), and the apparatus 100(C) does not transmit the stored information to the log information storage module 108 immediately after the information transmission instruction is received, but transmits the information to the log information storage module 108 at the date and time when the transmission of information to the apparatus 100(C) is required in the plan). These operations are repeatedly performed until all of the transmission plan for the information transmission instruction is executed.

A detailed example will be described with reference to FIG. 14. FIG. 14 is a flowchart illustrating an example of a process according to the second exemplary embodiment. A case in which the same debug log information collection plan as that shown in FIG. 13 is made will be described.

In Step S1402, an apparatus A 100A performs polling communication with the information processing apparatus 150.

In Step S1404, the information processing apparatus 150 transmits a debug log information collection plan to the apparatus A 100A.

In Step S1406, the apparatus A 100A transmits a debug log transmission instruction to an apparatus B 100B.

In Step S1408, the apparatus B 100B transmits debug log information to the information processing apparatus 150.

In Step S1410, the apparatus B 100B transmits a log transmission completion notice indicating the completion of the transmission of the debug log information to the apparatus A 100A.

In Step S1412, the apparatus A 100A transmits the debug log transmission instruction to the apparatus D 1000.

In Step S1414, the apparatus A 100A transmits the debug log transmission instruction to the apparatus E 100E.

In Step S1416, the apparatus D 100D transmits the debug log information to the information processing apparatus 150.

In Step S1418, the apparatus D 100D transmits the log transmission completion notice to the apparatus A 100A.

In Step S1420, the apparatus E 100E transmits the debug log information to the information processing apparatus 150.

In Step S1422, the apparatus E 100E transmits the log transmission completion notice to the apparatus A 100A.

In Step S1424, the apparatus A 100A transmits the debug log transmission instruction to the apparatus C 1000.

In Step S1426, the apparatus C 1000 transmits the debug log information to the information processing apparatus 150.

In Step S1428, the apparatus C 1000 transmits the log transmission completion notice to the apparatus A 100A.

Third Exemplary Embodiment

An example of the structure of a third exemplary embodiment is the same as the module structure according to the first exemplary embodiment shown in FIG. 1.

A communication analyzing module 104 of an apparatus 100(A) determines whether a communication module 102 receives a plan for a transmission order or a transmission date and time from an information processing apparatus 150.

When the communication analyzing module 104 determines that the plan for the transmission order or the transmission date and time is received from the information processing apparatus 150, a transferring module 110 of the apparatus 100(A) transmits the plan to, for example, an apparatus 100(B) in the plan through a communication module 102 and a communication line 199 on the basis of the plan. That is, the transferring module 110 transmits the plan.

For example, after a log information collecting module 106 transmits information stored in a log information storage module 108 of the host apparatus (for example, the apparatus 100(B)) to the information processing apparatus 150, a transferring module 110 of the apparatus 100(B) transmits the plan to the next apparatus 100(C) to which the plan is to be transmitted in the plan through the communication module 102 and the communication line 199 on the basis of the plan.

That is, in the third exemplary embodiment, the plan is relayed to the next apparatus 100. Each apparatus 100 transmits a process which is to be processed by the host apparatus (a process of transmitting information to the information processing apparatus 150) in the plan. Then, each apparatus 100 transfers the plan to the next apparatus 100 which is to perform the process. The control of the transmission of the plan is sequentially transferred to the next apparatus 100.

In the above description, the plan is transmitted. However, a plan from which a portion executed by the host apparatus is removed may be transmitted.

In the third exemplary embodiment, when each apparatus 100 transmits information, it is possible to transmit the plan without any change. However, when two or more apparatuses transmit information at the same time, the plan is transmitted considering a communication allowable range. Therefore, two or more apparatuses 100 to which the control of the transmission of the plan is transferred may be synchronized with each other. That is, when the plan is determined by the transmission order and there are plural apparatuses 100 in the same order, the apparatuses 100 are synchronized with each other so as to start the transmission of information at the same time.

A detailed example will be described with reference to FIG. 15. FIG. 15 is a diagram (including the flow of a process) illustrating an example of the process according to the third exemplary embodiment.

In Step S1502, an operator 1580 requests the information processing apparatus 150 to transmit the debug log information.

In Step S1504, an apparatus A 100A performs polling communication with the information processing apparatus 150.

In Step S1506, the information processing apparatus 150 requests the apparatus A 100A to transmit the debug log information.

In Step S1508, the apparatus A 100A transmits the debug log information to the information processing apparatus 150.

In Step S1510, the information processing apparatus 150 requests the apparatus A 100A to transmit the debug log information to an apparatus B 1005. The apparatus A 100A transfers the debug log information transmission request to the apparatus B 100B.

In Step S1512, the apparatus B 1003 transmits the debug log information to the information processing apparatus 150.

In Step S1514, the information processing apparatus 150 requests the apparatus B 100B to transmit the debug log information to an apparatus C 100C. Then, the apparatus B 1008 transmits the debug log information transmission request to the apparatus C 100C.

In Step S1516, the apparatus C 100C transmits the debug log information to the information processing apparatus 150.

In Step S1518, the information processing apparatus 150 presents the debug log information to a developer 1590.
